The problem was a bad keyway that is on the gear that turns the counterbalance shaft. The key had slight wear marks on both sides which allowed the sprocket on to move back and forth quite a bit. The counter balance shaft magnified the sound of that sprocket through the lower front part of the motor. I chaged the key and the bike purrs like a kitten again.
